Title:
[W250ENQ / W270ENQ, VIA VT1802, Speaker, Internal] Internal sub-woofer
does not work
Status in “alsa-driver” package in Ubuntu:
Confirmed
Bug description:
I recently bought a GenesisIV from pcspecialist.co.uk. It is a re-
badged Clevo W250ENQ.
The sub-woofer functions fine in Windows (which I have since removed),
but doesn't work in Ubuntu. speaker-test produces pink noise for the
left and right channel, but nothing for LFE (the sub-woofer). There's
a greyed-out sub-woofer volume slider in the pulseaudio widget (see
attachment), but I think this might be a red herring. I've tried
adjusting/unmuting all the channels in alsamixer, but doesn't seem to
do anything.
The module I'm using is snd-hda-intel and the codec is VIA VT1802.
